Network Variables (NVs) and Configuration Properties (CPs) List

Table 1 shows the NVs and CPs for the TEC2245-2 Series thermostat. Each Network Variable Input (NVI), Network Variable Output (NVO), and Network Configuration Input (NCI) has a reference number, and some objects have a subcategory number. The Sub column lists the thermostat’s Enumeration (Enum) options for the NV or CP. The Byte column shows the actual byte number used for commanding the NV nvoSccStatus and nciGenOpts NVs.

Note: When you use a LONWORKS® network configuration tool to view the Status/Command screen:

• nvoSccStatus is a 64 bit (bit 0 to bit 63) field.

• nciGenOpts is a 25 bit (bit 0 to bit 24) field. Table 1: NV and CPs By Model (Part 1 of 3)No Sub Bit NV or CP Name Model

Commissioning the Thermostat Using a LONWORKS Network Configuration Tool

A thermostat must first be commissioned using a LONWORKS network configuration tool before it can be added to the LON Integration of the Network Automation Engine (NAE). This process implements the initial configuration and assigns the Neuron® ID of the thermostat.

Understanding LONWorks Network Configuration Tools’ Differences

LONWORKS network configuration tools use different numbering schemes in their Status/Command screens. Metasys system Connectivity to LONWORKS network (MCL) Tool begins its first entry with byte 0, while Lonwatcher begins with byte 1. Figure 1 shows the nciGenOpts Status/Command screen in MCL Tool on the left, with the equivalent Lonwatcher screen on the right.

MCL Tool Bit 0 to Bit 63 Byte 0 to Byte 24

Lonwatcher Bit 1 to Bit 64 Byte 1 to Byte 25

18

Changing the Thermostat’s Settings Using a LONWORKS Network Configuration Tool

Once a thermostat is configured and online, you can use a LONWORKS network configuration tool to change its settings. This means you do not have to go to the thermostat and manually make the changes.

To change most of the thermostat’s configuration properties:

1. Using a LONWORKS network configuration tool, open the thermostat’s nciGenOpts Status/Command screen.

2. From Table 8, find the desired configuration property and enter the corresponding value into its respective byte location in the nciGenOpts Status/Command screen.

Note: Some configuration properties require you to enter a range number in a specific byte location, followed by a corresponding value in the next byte location. You must enter both the range number and value before commanding the thermostat.

3. Enter additional configuration property changes if desired.

4. Command the thermostat. The new configuration changes are implemented.

Note: The Lockout settings must be made at the thermostat.

Service PinTo broadcast the thermostat’s Neuron ID over the LONWORKS network:

1. Simultaneously press and hold the Up Arrow and Down Arrow for 5 seconds. A small green light under the thermostat cover (on the left edge when facing the thermostat) flashes to indicate the thermostat’s Neuron ID is being broadcast on the LONWORKS network.

2. For manual entry, the Neuron ID is also on a label on the Echelon® chip under the thermostat cover.

Adding a Thermostat to the NAEOnce you commission a thermostat, you must add it to the NAE before its points can be mapped. To do this, select the LONWORKS Integration under the NAE (refresh the tree view if required to see a newly added LONWORKS Integration) and choose Field Device from the Insert menu. Assisted Definition using Auto Discovery is the easiest way to add a new thermostat online; however, this requires that the new thermostat is connected and ready to communicate. Refer to the LONWORKS Network Integration with NAE Technical Bulletin (LIT-1201668) for instructions on how to add a LONWORKS device.


19

LONWORKS Thermostat Mapping

PreparationBefore mapping a TEC2245-2 Thermostat into an NAE:

1. Decide which point objects within the thermostat need to be mapped. Only map the point objects that need to be viewed on a regular basis, since excessive mapping lowers system performance. Suggested point objects for mapping include: Room Temp, System Mode, Fan Status, Occupied Heat Setpoint, Occupied Cool Setpoint, Unoccupied Heat Setpoint, and Unoccupied Cool Setpoint. In addition, alarm points may be mapped if they are used, and other point objects may be mapped if required. Use the Engineering view to examine infrequently used point objects.

2. Verify that a LONWORKS Integration is defined in the NAE. The commissioned thermostat is mapped as a LONWORKS device under a LONWORKS Integration. Refer to the LONWORKS® Network Integration with NAE Technical Bulletin (LIT-1201668) for instructions on how to define a LONWORKS network Integration.

At this point, you can map the thermostat and the required point objects inside the thermostat.
